A B.C.R.A. grade 5 survey was in progress and was being conducted by the Chelsea Speleological Society. Almost 75% of the known cave was drawn to this grade. This survey has now been discontinued, and may no longer be available for sale.

I offer my most sincere thanks to Steve. Between mid 1995 and early 2007, he had very generously hosted my Ogof Draenen description on his site, helped merge countless updates into it, fixed more typôs and grandmatickle errors than I have had hot baths, and made sure that the description has been available to you, the caver, for almost as long as the Web itself has existed.
But the time came for me to take over hosting of the description for myself. This is the current home for the Draenen description, and it will remain here for the foreseeable future. I intend to keep it up to date here, to the standard that you have come to rely on. Enjoy.
